物理作图，是指以物理尺度(如碱基对的基因)标明各种遗传标记在基因组上的位置和距离。
本发明不仅可利用该无毒基因的标记作探针，而且为进一步通过物理作图法克隆该无毒基因奠定了基础。
The invention can not only make use of the nontoxic gene marker as gene probe, but also set foundations for further clone of the gene through physical mapping.
许多物理实验，若用传统的实验数据处理方法则存在着计算量大、作图误差大、公式变换复杂、所得结果不直观简洁等诸多问题。
The data processing of physics experiment with traditional method has some problems, such as generous calculation, diagraph error, complex formula-transform, indirect and complicated result.
比较显示，图谱上所有标记的顺序与其物理顺序完全一致，证明了利用ILP标记进行遗传作图的可行性和有效性。
Comparison showed that the order of the markers in this map was exactly the same as their physical order, verifying the feasibility and efficiency of using ILP markers for genetic mapping.
